WebThe graph theory can be described as a study of points and lines. Graph theory is a type of subfield that is used to deal with the study of a graph. With the help of pictorial representation, we are able to show the mathematical truth. The relation between the nodes and edges can be shown in the process of graph theory. Several important classes of graphs can be defined by or characterized by their cycles. These include: Bipartite graph, a graph without odd cycles (cycles with an odd number of vertices)Cactus graph, a graph in which every nontrivial biconnected component is a cycleCycle graph, a graph that consists of a single … See more In graph theory, a cycle in a graph is a non-empty trail in which only the first and last vertices are equal. A directed cycle in a directed graph is a non-empty directed trail in which only the first and last vertices are equal.

WebAn induced path is sometimes called a snake, and the problem of finding long induced paths in hypercube graphs is known as the snake-in-the-box problem. Similarly, an induced cycle is a cycle that is an induced subgraph of G; induced cycles are also called chordless cycles or (when the length of the cycle is four or more) holes.
